You realize the authentication is done top to bottom? The first line that
matches wins :) So if you have a matching "trust" line before your "md5" line
then it will not use md5.
For a better explanation:
http://www.postgresql.org/docs/8.2/interactive/auth-pg-hba-conf.html
"Each record specifies a connection type, a client IP address range (if relevant
for the connection type), a database name, a user name, and the authentication
method to be used for connections matching these parameters. The first record
with a matching connection type, client address, requested database, and user
name is used to perform authentication. There is no "fall-through" or "backup":
if one record is chosen and the authentication fails, subsequent records are
not considered. If no record matches, access is denied."
